CONTAINER.

. Application filed December 24, 1919. Serial No. 347,201.

I Relating to Containers, of which the following is a specification taken in connection with the accompanying drawing. 7

This invention relates especially to containers for shipping purposes in which the parts are so constructed, fastened and sealed as to be practically non-pilferable. The container which may be made of corrugated paper board, fibre board or other suitable material may comprise a container body formed of one or more pieces or sections of such material, and for relatively small containers a single strip or piece of corrugated paper having transversely scored portions may be folded up into the desired form. The side seams between the adjacent ends of such container body rnaterial, which may if desired have cooperating bevelled edges, may be secured by a connector or retainer strip of adhesive or gummed cloth or paper tape which may be secured to the outside of the container body and have inturned ends foldedaround the edge portions so as toengage, and if desired overlap, each other on the inside of the container body. It isalso desirable to provide the container body member, or the top or bottom cover cooperating therewith, with an outer projecting edge flange so as to form a stepped or rabbeted edge on the container body, for instance, within which the top or bottom cover or both, may be received and cemented in such way that the inner concealed portions of these cooperating members are glued or cemented together to still further minimize pilfering or facilitate detection thereof. The creased or scored seam portions of the body may be reenforced by suitable tapeinside or outside of the container body and the other edge seariis thereof may be provided with retainer strips of gummed tape or the like which preferably have inturned ends for a similar purpose When the top and bottom of the container have been secured in place the edge seams around the same may be closed by suitable sealing strips of gummed cloth or paper tape which preferably have flexible or pliable seam portions to facilitate attachment. I

In the .accompanying drawing showing in asomewhat diagrammatic way an illustrat ve embodiment of this invention,

Fig. 1s a perspective View of a container partly in section. I

, Fig.2 is a partial transverse section thereof taken substantially along the line 2+2 ofFig. l; and

F 1g. 3 1S a diagrammatic perspective view showing a way in which the stepped edge of the container body may be formed.

In the illustrative embodiment of the in-- ventlon which is shown in Fig. 1 of the drawing the container body which may as indicated be formed of corrugated paper board may be creased or scored at the desired points to form the corner portions or seams, such as 13 as shown in Fig. 2, and these portions may be reenforced by the fold reenforcing tape, such as 11, which may advantageously be forced into the fold or crease for this purpose. When these creases extend transversely across the corrugated paper definite sizing of the parts 18 promoted so that they are readily interchangeable as well as I given increased strength under these conditions. In the case of relatively small containers the container body may often be formed of a single strip or piece of corrugated paper board, fibre board or the like from. which the sides 1, 2, 3 and 4 may be formed, although for larger boxes or containers two or more pieces ofmaterial may be used to form the body, the edge seams between the pieces of body material being preferably secured by body connector or retainer strips, such as 15, which may be pasted or otherwise adhesively secured on the outside of the body seam and may have portions'l8 extending around the edgesthereof so as to form inturned ends 16, 17 secured on the inside of the container body to give greater strength and much greater protection against pilfering. If desired also other retainer strips, such as 35, may in anycase be used or arranged on the other edge seams of the container body so as to give similar protection against pilfering.

In many cases it is advantageous to form the container body with a stepped or rabbeted edge portion or with -a projecting edge flange such as 5 which may extend around one or both ends of the container body to accommodate the top or bottom which cooperate therewith, For this pur pose the corrugated paper board or other material may advantageously be slit and then formed into this stepped or rabbeted configuration, one arrangement for effecting this being diagrammatically shown in Fig. 3. A slitting device such as the rotaryslitting saw 23 may first engage the edge 2-1 of the sheet of corrugated paper board or the like and then after the upper portions have been slit or cut through in this Way along the line 25 a rotary knife or planer device such as 22, may readily and rapidly remove the upper portions of this edge so as to leave a stepped edge on the material comprising an inner edge 7 and an inner face 5 which is a projecting edge flange and extends part or all the Way around the top and bottom of the container body. It is of course understood that this container body is preferably given such'a projecting edge flange configuration before the connector or etainer strips of gummed cloth or paper tape, such as 15, 35, are applied thereto, so that these strips can be closely pasted or cemented to the edge flange to take up a minimum of space at these points.

The top and bottom of the boX, such as 10 14, may be formed of corrugated paper board or other material of such size as to lit into the container body preferably Within the edge flanges thereof and these members may advantageously be glued or cementedin place as by the glue 2'? indicated in Fig. l as extending Within this stepped or flanged edge portion of the container body so as to cement the concealed inside portions of these cooperating elements which of course makes it more dii'iicult to separate the parts Without such tearing or other injury as makes the detection of piltering easy and inevitable. The inturned ends of the retainer or connector strips also contribute to this result since they cannot of course be applied after the container cover or top is in place in such Way as to properly secure their inturned enc s in the original'position. Nhen the top and bottom are secured in place the seams around these members may beclosed by the use of sealing strips of cloth or paper tape,

such as '6 and 9 which may be pasted over these seams to thus give added protection against dirt and moisture and to give addi 'tional strength and security to the package.

This i. vention has been described in connection with a number of illustrative embodiments, forms, portions, parts, material-s, arrangements and methods 01' manufacture and useyto the de ails of which disclosure the invention is not of course to be limited, since What is claimed as new and What is desired to be secured by Letters Patent is set forth in the appended claims.

1. The non-pilferable shipping container comprising 'a container body formed of a single piece of corrugated paper board material having each seam Where the ends of the body material. are joined secured by a retainer strip of tape adhesively secured to the outside of the body material and having 'inturned ends which are brought around the edges of the body material and secured to the inside ot the container body,the edges of said container body having a stepped form to provide a projecting outer flange and a cooperating top and bottom formed of corrugated paper board cooperating with the stepped edge portions otsaid container body and cemented Within the projecting flanges thereof.

2. The no'n-pili'erable shipping container comprising a container body formed of paper board material having each seam Where the ends of the body material are joined secured by a retainer strip of tape adhesively secured to the outside of the body material and having 'inturned ends Which are brought around the edges of the body material and secured to the inside oi the container body, the edges of said con-- tainer body having a stepped form to provide a projecting-outer flange and a topand bottom cooperating With the stepped edge portionsot said container body and cemented Within the projecting flanges thereof.
